Overview
The Littelfuse T106D2 is a sensitive-gate silicon controlled rectifier (SCR) designed for switching and controlling AC or DC power in electronic circuits. It features an off-state voltage of 800V and operates within a temperature range of -40°C to 125°C. The device is housed in a TO-220 Non-Isolated Tab package, with some sources indicating a TO-202 configuration. It supports a holding current maximum specification and is rated for 4A current handling in certain configurations.
Feature Summary
- Sensitive gate architecture for reliable triggering
- Robust thermal performance across wide operating temperatures
- Non-isolated tab design for efficient heat dissipation
Applications
- AC power switching circuits
- DC power control applications
- General purpose electronic circuit protection
Procurement Notes
Verify the specific package designation, as documentation references both TO-220 and TO-202 formats. Confirm the exact voltage rating context, noting discrepancies between 400V and 800V specifications in different sources. Ensure the manufacturer is correctly identified as Littelfuse or Hamlin/Littelfuse to guarantee component authenticity and compliance with RoHS3 standards.
Selection Notes
Select this component when a sensitive-gate SCR is required for moderate power switching tasks. Consider the thermal management capabilities provided by the non-isolated tab design for high-temperature environments. Evaluate the specific voltage and current requirements against the documented 800V off-state and 4A ratings to ensure adequate safety margins for the intended application.
Part Context
The T106D2 belongs to the TENCO Technology series of sensitive SCRs manufactured by Littelfuse. These components are engineered for robust performance in industrial and consumer electronics. The part represents a standard solution for phase control and power regulation, leveraging established thyristor technology for reliable operation in demanding electrical environments.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before attempting substitution, as package variations (TO-220 vs. TO-202) may impact mechanical integration.
